Tire inspection

 

The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.

 

Tire information

 

This motorcycle is equipped with panel
wheels and tube tires.

WARNING

 

EWA10461

 

The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, which

 

could lead to an accident.

 

After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.

WARNING

 

EWA14390

 

 

Have a Yamaha dealer replace
excessively worn tires. Operat-
ing the motorcycle with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.

 

 

The replacement of all
wheel-and brake-related parts,
including the tires, should be
left to a Yamaha dealer, who has
the necessary professional
knowledge and experience.

 

 

It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
